SPECIFICATION forming part pffitetters Patent No. 702,7818, datedJuneil'?, 1902.

Atpiicanon inea February' 1o', 1962. .serinnoij'e3,4so. montati-)ff Toall whom it mayconcern Be it known that I, SAMUEL-GECZYNSKI, civilengineer, a subject of the vEmperorof Russia, residing at No. 77Bernauerstrasse, Berlin, Kingdom of Prussia, and Empire of Germany, haveinvented certain new and useful Improvements in Machines with CircularKnives for Cutting Textile and other Fabrics, whereof the kf ollowingisa specification.

This invention -relates to machines for cutting textile and otherfabrics;v and ithas for its object to improve upon the construction andthe operation of machines ofthis class now in use which employ a'rotarycuttingknife. f

The invention consists of certain parts and combinations of parts,,whichwill be hereinafter fully described, and pointed out in theappended claims.

Referring to the drawings, Figure l shows the improved machine inlongitudinal section on the line A B lo'okinginithe direction o-f arrow4, Fig. 2. Fig. 2 is a longitudinal section on the line C Dlooking inthe direction of arrow 5, Fig. 1. Fig. 3 is a section on the line E F ofFig. 1.

The invention comprises alower casing and an upper. casing 7,'providedlwitha downwardly-extending hollow pivot 8, which isrotatablymounted in an opening in the lower casing 6. .Avertical shaft 9 issupported within the hollow pivot 8 and the bushing 10,which is alsomounted in the opening in the lower casing 6, and said shaft 9 is heldagainst axial movement within the hollow pivot and the bushing byflanges 11 and 12.

Upon the ends of the shaft 9 are lsecured worm-wheels 13 and 14;, theone upon the up-k per end meshing with a worm-wheel 16 upon adriving-shaft 15, mounted in the upper casing 7, and the worm-wheel 14upon the lower f end of the shaft 9 meshing with a worm-wheel 18 uponashaft '17, mounted in the lower casing 6. It will thus be seen that theupper casing is adapted to be rotateduponthe lower casing, so `thatpower .maybe 'applied to the .shaft 15 from anyposit'ion.

Upon the shaft 17 is secured a'large spurwheel 19,"which'meshes with asmall spurwheel 22 upon the shaft 20, which shaft carvriestherotaryknife or cutteri2lv, the upper casing being cut awaylat23, sothat the same may be exposed'for use.A

Both of the casings and 7 ymay be provided with removable covers24= torender the parts within said casings accessible.

The machine is drivenby a iiexible shaft or any other suitable` means.,y

Furthermore, when the1driving#s`haft, 1 5 is slowly rotated it'willbeclear "thatthe circular cutter 21.`willrapidlyrotata as a result of4the ratio existing hetween'the wheels 19 and 22, without, however,causing by this speed 'of the cutter-shaft the disturbinglvibrations, l

as when the driving-shaft 15 itself isrotated 'at a greater speed.,

To obviate lubricating-oil flowing from the bearings of the shafts 15,9, and v17 into the `casing 6, the said casing is so shaped that it'forms a kind of container 26, in which such oil .may collect. Y 1
